CONSTRUCTION OF RAILWAY-TRACKS AND THE CONSTITUENT PARTS THEREOF.

SI EGIEICATIQN forming part of Letters Patent No. 348,877, dated September 7, 1886.

(No model To all whom it may concern: I

Be it known that I, HENRY PARKE ADAMS, of the city and county of Albany, in the State of New York, have invented new and useful Improvements in the Construction of Railway- Tracks and the Constituent Parts Thereof, of which the following is a specification.

Owing to the growing scarcity and expense of wood of suitable quality for the ties used [0 in laying railway-tracks, the propriety of continuing the use of that material has become a most serious question with those having the construction of railways in charge.

The objects of my invention are, first, to afford facilities for constructing railway-tracks entirely of metal; second, to dispense with the use of spikes for securing the rails, and third, to make the metallic ties serve as a gage for spacing the rails and for clamping said railsin place. These objects I attain by means of the constructions shown in the ac companying drawings, which being herein referred to form part of this specification, and in which- Figure 1 is a plan view of a railway-track containing my improvements; Fig. 2, an enlarged plan view of my metallic tie with the chainplates arranged to clamp the outside edges of the rails; Fig. 3, a side view of the same; Fig. 4, an enlarged plan view of my metallic tie with chairplates arranged to clamp against the inside edges of the rail; Fig. 5, a side view of the same. Figs. 6 and 7 are respectively a plan view and side ele- 5 vation of a modified form of chair-plate for my metallictic; and Figs. 8 and 9 are respectively a plan view and transverse section of another modified form of said chair-plates.

As shown in the drawings, the track-railsA a e are of the ordinary T-rail variety, which my invention does not aii'ect.

B and B" are metallic ties composed of the chair-plates b and tie-bolts Z).

The chair-plates 1) (shown in Figs. 1 to 5) are of cast metal. Said chair-plates have on their upper surface hooked lugs or lips b, which are adapted to hook over the bottom flange of the rail A, as shown in Fig. 5, and on their under sides end flanges, b through which the tie-bolts I) pass. Said end flanges may be connected by longitudinal ribs 1), so as to give great strength to the plate I).

As shown in Figs. 5 to 9, the chair-plates b are madeof wrought-iron, rolled or otherwise formed, with the longitudinal ribs 1), the said ribs being cut off flush with the under side of the top plate to the length required to reach between the two end flanges, b, which are formed by turning down (as indicated by dot ted lines in Fig. 7) the projecting ends of the top plate at right angles to the plane of said top plate. The hooked lips I)? in said modifications are formed by making incisions through the top plate to cut one end and one orboth sides of each lip free from the top plate, 6 5 and then bending the lip in the form required, the said cutting and bending being readily effected at one operation by means of a proper punch. The metallicties B and B only differ from each other in having their chair-plates 1) arranged in a different manner on the tiebolts 1), and in having means for keeping the chairplates apart'that is to say, the ties B have their chair-plates fixed on the tiebolts b, so that the hooked lips I) will be turned toward each other, and with no interposing obstacle between said chair-plates; but in the ties B the chair-plates I) have their hooked lips I) turned from each other, and said plates are kept apart either by collars b formed on the tiebolts Z), as shown in Fig. 1, or byasleeve, b, of the required length, which fits loosely on the tiebolt, as shown in Figs. 4- and 5.

In laying the track the ties B and B are placed alternately, as shown in Fig. 1, the tics B serving as a gage to space the rails at the required distance apart, and the ties B clamping the rails against the lips I) of the ties B. As fast as the track is laid in place earth, gravel, or othersuitable material should be tamped underneath the chair-plates until they obtain a solid bearing.

I am aware that tie-bolts have heretofore been used for spacing and securing potsleepers and othersupports for railway-rails, therefore I do not broadly claim the use of said bolts for that purpose; but

I claim as my invention- In a railway-track, the combination, with the track-rails, of metallic ties each composed track-rail, and screw tie-bolts whereby said of a chair-plate provided with am hooked lip or tracks are spaced and secured, as herein speei lips adapted to engage with one edge of the fied.
